Now that I'm a more experienced designer in real estate, I would love to customize my kitchen more with different materials, unique tile, and more unique pulls/knobs but having a large, clean kitchen was extremely appealing to me as a first-time buyer 4 years ago.

"Oh the customer insisted on buying the materials, it's not my fault"

Quote from @Dave Foster: @Jason Sung There is actually no statutory holding period.

Some states do have special guidelines or customs that differ from state to state, but this is a minority of situations.  

I know I work for the company, but I'm also an All In One Loan customer.

And the customer would think we were responsible .

It's a tremendous benefit to you to have a customized lease by a legal expert.

You have another customer to manage. 

Plus they are all busy doing occupant custom remodels.Flippers and landlords like me have alwyas been forced into being hands on, the crew chief, over handymen and a few licensed trades.   

I think you could split after sale for a non-taxable event, the total basis transferred in would be split across the two "new" properties.Calling @Dave Foster to give his insights here, lots going on in this one.
